Autoit hotkeyset Function

Hotkeyset ("hotkey" [, "function name"])

Parameters

Hotkey	The hotkey to be set,The key format is the same as that used by the send () function.
Function Name	[Optional parameter] Name of the function to be called after pressing the hot key. If this parameter is left blank, the previously set Hot Key is revoked.

Return Value

Successful:	The return value is 1.
Failed:	The return value is 0.

Note:

Each scriptProgramUp to 64 hotkeys can be registered simultaneously.

If two autoit scripts have the same hotkeys, you should avoid running these two script programs at the same time (otherwise the second script will not be able to capture the hotkeys, except that the first script stops running or the conflicting Hot Key is revoked before the Second Script sets the hot key ).

After you press the hot key, * normally * the currently running autoit function/statement is interrupted, and the user function associated with the hot key is run until the operation is completed or interrupted. Of course there will be some exceptions:
1) if the current (running) function is a "blocking" function, the key-click action will be buffered and will not continue until the blocking function completes the operation. Msgbox and fileselectfolder are typical blocking functions. You can try the hotkey shift-alt-D defined in the following example script.
2) if you select the pause script on the autoit tray menu, any hot keys that are pressed during the pause will be ignored.

Hot keys that cannot be set:

CTRL + ALT + Delete	Reserved by Windows
F12	It is also retained by windows and involves APIs.
Enter on the keypad	Use {enter} to capture both the primary key and the Enter key on the keypad.
Win + B, D, E, F, L, M, R, U; and win + Shift + m	These are built-in windows shortcut keys. Note: Windows + B and Windows + L are reserved only for Windows XP and later systems.
ALT, Ctrl, shift, win	These are auxiliary buttons!
Others	Any global hotkeys defined by third-party software, any hotkeys consisting of two or more "base keys" (for example, '{F1} {F2 }'), any type such as '{lalt}' or '{altdown.

After a hot key is set, autoit will try to capture the specified key event but will not pass it to the activation program, but there is also an exception: press the lock key (including numlock, capslock, and scrolllock) to switch its status at any time! If you want to send the captured hotkey event to the activation program, you must cancel the hotkey before callingSendOrControlsendFunction:

; Capture and pass button events
Hotkeyset ("{ESC}", "captureesc ")
Func captureesc ()
;... Various tasks can be defined here
Hotkeyset ("{ESC }")
Send ("{ESC }")
Hotkeyset ("{ESC}", "captureesc ")
